Thanks for answering fast Ray. I have used the Webassist / Database / Model Database following the tutorials. I made all the joins among the tables, all good. Then I proceed to create a record set , again following the tutorial, as soon as I click on Query Builder to create a more complex query I get the message. But now that you mention that there's no select to work from, I thought I was able to create one from scratch using the query builder as in the tutorial, but I will try what you suggest and let you know. Thanks, wait for my reply in a few!.
